LINE-CASTING MACHINE.

Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed December 30, 1911. Serial No. 668,650.

circulating matrices are employed.

In practice certain letters oi the alphabet, such as e, i, etc, are used with much greater frequency than others. It is, therefore, a common practice to devote two or more channels of the magazine to matrices containing the same character, and to provide in connection with the linger keys which release the matrices mechanism to cause their release from the associated channels in a definite order or succession, as shown, for example, in Letters Patent of Great Britain llo. 19,017 or the year 190.5,and in Letters Patent of the United States No. 658,740, dated September 25th, 1900.

The object of my invention is to provide a more simple and direct mechanism through which matrices may be discharged from two adj oi nin g magazine channels alternately.

To this end, it consists in combining with two escapeinents, a single reed or keyboard connection, and an intermediate shifting member through which the reed actuatcs the two escapements alternately.

in the drawings: Figure 1 is a vertical section from front to rear through the escapement mechanism combined with my im proved device. Fig. 2 is a rear elevation of the same.

Referring to the drawings: A represents an inclined longitudinally channeled magazine adapted to receive and guide the matrices B.

7, C represent cscapcment levers pivoted at c and havinpat opposite ends two" lips which, by the vibrationsozt the escapenient, are projected upward alternately into the matrices and release them one-at a time.

l1) isa spring which holds theescapement normally in the position shown. v

Matrices containing the same character will be carried in the two channels con trolled by the escapements C and C.

So far as described the" parts are similar to those now in commercial use.

E, E are two arms or levers mounted in the main frame on horizontal pivots, and adapted to act upward against the respective cscapements for the purpose of operating them.

F is an escapcmcnt actuating reed, vertically guided, and having its upper end bifurcated or "formed with two arms, to act on the respective levers E, E. This reed 'F will be connected. by any suitable devices with a finger key representing the matrix character in the two channels, for instance, mechanism such as shown in Letters Patent of the United States to Philip T. Dodge, No. 530,931.

The upper ends of the reed F do not act directly on the levers E, E, but communi- Cate motion to them alternately through an intermediate dog G. This dog, of T-form, is provided at the upper end with a suspending pivot or trunnion g, mounted to travel in a V-shapcd groove in the stationary plate 5, the lower side of this groove be ing formed by a spring ll, secured at. one end only by a screw it, and bent upward into the groove or notch as shown. The form and arrangement of the parts is such that this dog is lifted by the two ends of the reed F alternately, and caused by the spring or switch H to turn to the right or left, so

that its lower end stands normally under.

the respective levers E, E and over the corresponding ends of the reed F. When the dog is in the position shown in Fig. 2 it will be lifted by the left arm of the reed F, and will communicate motion through the overlying lever E to the cscapement G, thereby effecting the deliveryiof a matrix from one of the channels. -As the dog rises during this action its upper end passes over the raised point of the spring H; and when the reed descends the dog falls to the position shown in dotted lines, with itsend between the right hand lever ll) and the right arm of the reed F, so that when the reed is again raised the dog will leave the lever E at rest and impart motion through the lever E to the escapement C,

it will be seen, therefore, that the successive actions of the reed cause the dog G to shift to and fro, right and left, so as to communicate motion from the reed to the levers E, E and the connecting escapement's, alternately.

It will be obvious to the skilled mechanic that the form of the dog, and the details, may be materially modified Within the range of mechanical skill without departing from the limits of my invention. It will also be understood that the dog Gr instead of operating on the escapements through the levers E, E may be located bet-ween them and arranged to operate directly upon them.

While I prefer to employ the form of escapement herein shown, I may employ escap ements such as shown in Let rs Patent of the United States No. 436,532, or escapements of any equivalent form.

Having described my invention, what I claim is:

1. The combination of two escapements,

an actuating reed, and an intermediate independently supported dog to communicate motion from the reed to the two escapements alternately, said dog arranged to move laterally from one operative position to another under the influence of the reed.

-2. In combination, the two escapements, the levers for communicating motion thereto, the forked reed, the intermediate dog 0 erated thereby, and means for shifting t e dog to the right and left as it is operated by the reed.

3. In combination, the two escapements C and C, actuating levers E and E, the reed,

the laterally movable and independently supported dog located between the reed and the levers, and a switch mechanism whereby the operation of the reed shifts the dog into operative relation to the two levers alternately.

4. As a means of communicating motion to two escapements alternately, a lifting and the spring switch H, whereby the actuation of the reed shifts the dog from one operative position to another. 6. The combination of two escapements, actuating means therefor comprisingtwo distinct operating members. one for each escapement, and a device controlled by said actuating means t" interpose itself between one or the other of the said escapements and the corresponding operating-member, to establish the connection between the escapement and the actuating means.

Intestimony whereof I hereunto set my hand this 20th day of December, 1911, in the presence of two attesting witnesses.
